BackgroundCognitive behaviour therapy (CBT) is an effective treatment for obsessive–compulsive disorder (OCD) but access to CBT is limited. Internet-based CBT (ICBT) with therapist support is potentially a more accessible treatment. There are no randomized controlled trials testing ICBT for OCD. The aim of this study was to investigate the efficacy of ICBT for OCD in a randomized controlled trial.MethodParticipants (n=101) diagnosed with OCD were randomized to either 10 weeks of ICBT or to an attention control condition, consisting of online supportive therapy. The primary outcome measure was the Yale–Brown Obsessive Compulsive Scale (YBOCS) administered by blinded assessors.ResultsBoth treatments lead to significant improvements in OCD symptoms, but ICBT resulted in larger improvements than the control condition on the YBOCS, with a significant between-group effect size (Cohen's d) of 1.12 (95% CI 0.69–1.53) at post-treatment. The proportion of participants showing clinically significant improvement was 60% (95% CI 46–72) in the ICBT group compared to 6% (95% CI 1–17) in the control condition. The results were sustained at follow-up.ConclusionsICBT is an efficacious treatment for OCD that could substantially increase access to CBT for OCD patients. Replication studies are warranted.
Internet-delivered CBT has specific effects that cannot be attributed only to treatment credibility, expectancy of improvement, therapeutic alliance, or attention. Furthermore, a treatment based on exposure exercises specifically tailored for IBS may be a better treatment option than general stress and symptom management for IBS patients. ICBT is a promising treatment modality for IBS as it can be offered to IBS patients in much larger scale than conventional psychological treatments.
Background and AimsCognitive behavioral group therapy (CBGT) is an effective, well-established,
but not widely available treatment for social anxiety disorder (SAD).
Internet-based cognitive behavior therapy (ICBT) has the potential to
increase availability and facilitate dissemination of therapeutic services
for SAD. However, ICBT for SAD has not been directly compared with in-person
treatments such as CBGT and few studies investigating ICBT have been
conducted in clinical settings. Our aim was to investigate if ICBT is at
least as effective as CBGT for SAD when treatments are delivered in a
psychiatric setting.MethodsWe conducted a randomized controlled non-inferiority trial with allocation to
ICBT (n = 64) or CBGT (n = 62)
with blinded assessment immediately following treatment and six months
post-treatment. Participants were 126 individuals with SAD who received CBGT
or ICBT for a duration of 15 weeks. The Liebowitz Social Anxiety Scale
(LSAS) was the main outcome measure. The following non-inferiority margin
was set: following treatment, the lower bound of the 95 % confidence
interval (CI) of the mean difference between groups should be less than 10
LSAS-points.ResultsBoth groups made large improvements. At follow-up, 41 (64%)
participants in the ICBT group were classified as responders (95% CI,
52%–76%). In the CBGT group, 28 participants
(45%) responded to the treatment (95% CI,
33%–58%). At post-treatment and follow-up respectively,
the 95 % CI of the LSAS mean difference was 0.68–17.66
(Cohen’s d between group = 0.41)
and −2.51–15.69 (Cohen’s d between
group = 0.36) favoring ICBT, which was well within the
non-inferiority margin. Mixed effects models analyses showed no significant
interaction effect for LSAS, indicating similar improvement across
treatments (F = 1.58;
df = 2, 219;
p = .21).ConclusionsICBT delivered in a psychiatric setting can be as effective as CBGT in the
treatment of SAD and could be used to increase availability to CBT.Trial RegistrationClinicalTrials.gov NCT00564967
Therapist-guided ICBT is a promising low-intensity intervention for adolescents with OCD and has the potential to increase access to CBT. It might be particularly useful in a stepped-care approach, in which a large proportion of patients with moderately severe OCD could first be offered ICBT, thus freeing limited resources for more complex cases.

Internet-based CBT is an efficacious treatment for hypochondriasis that has the potential to increase accessibility and availability of CBT for hypochodriasis.
Measurements of subjective quality of life (QoL) are an important complement to symptom ratings in clinical research and practice. Despite there being several established QoL self-rating scales, we identified a need for a freely accessible, easy-to-use inventory, validated for use with both clinical and non-clinical samples, based on the overall life satisfaction conceptualization of QoL. The Brunnsviken Brief Quality of life scale (BBQ) was designed to meet these requirements. Items were selected by performing a factor analysis on a large data-set of QoL ratings collected previously. Six life areas (Leisure time, View on life, Creativity, Learning, Friends and Friendship, and View of self) were identified as important for overall QoL and were included in the BBQ. A psychometric evaluation was performed using two independent samples: healthy undergraduate students (n = 163), and a sample seeking treatment for social anxiety disorder (n = 568). Results suggested a unifactorial structure, with good concurrent and convergent validity, high internal and test-retest reliability, and accurate classification ability. We conclude that the BBQ is a valid and reliable measure of subjective QoL for use in clinical and research settings. The BBQ is presently available in 31 languages and can be freely downloaded from www.bbqscale.com.
<b><i>Introduction:</i></b> Worries about the immediate and long-term consequences of the COVID-19 pandemic may for some individuals develop into pervasive worry that is disproportionate in its intensity or duration and significantly interferes with everyday life. <b><i>Objective:</i></b> The aim of this study was to investigate if a brief self-guided, online psychological intervention can reduce the degree of dysfunctional worry related to the COVID-19 pandemic and associated symptoms. <b><i>Methods:</i></b> 670 adults from the Swedish general population reporting daily uncontrollable worry about COVID-19 and its possible consequences (e.g., illness, death, the economy, one’s family) were randomised (1:1 ratio) to a 3-week self-guided, online cognitive behavioural intervention targeting dysfunctional COVID-19 worry and associated symptoms, or a waiting list of equal duration. The primary outcome measure was a COVID-19 adapted version of the Generalised Anxiety Disorder 7-item scale administered at baseline and weeks 1–3 (primary endpoint). Follow-up assessments were conducted 1 month after treatment completion. The trial was registered on ClinicalTrials.gov (NCT04341922) before inclusion of the first participant. <b><i>Results:</i></b> The main pre-specified intention-to-treat analysis indicated significant reductions in COVID-19-related worry for the intervention group compared to the waiting list (β = 1.14, <i>Z</i> = 9.27, <i>p</i> < 0.001), corresponding to a medium effect size (bootstrapped <i>d</i> = 0.74 [95% CI: 0.58–0.90]). Improvements were also seen on all secondary measures, including mood, daily functioning, insomnia, and intolerance of uncertainty. Participant satisfaction was high. No serious adverse events were recorded. <b><i>Conclusions:</i></b> A brief digital and easily scalable self-guided psychological intervention can significantly reduce dysfunctional worry and associated behavioural symptoms related to the COVID-19 pandemic.
